A study was conducted to determine the highest degree of low level enroute navigational effectiveness and resultant drop accuracy attainable under various weather conditions in the C-130 type aircraft utilizing airborne navigational aids presently installed in C-130 aircraft or currently available from within Air Force resources or from industry and operable without modification to the aircraft. This project was conducted in two basic phases without ground navigational aids and with ground electronic aids available on the drop zone. It was determined that successful low level radar enroute navigation can be realized down to altitudes of 500 ft absolete altitude provided certain prerequisites are met. Utilizing Standard Calculated Air Release Point CARP procedures, circular errors for drops with no ground support were dependent on drop altitude and the availability of mandatory radar return references at periodic intervals along the flight course.
